What is the minimum height for traffic cones used on nighttime or high speed roads?

• A. 24 in
• B. 28 in
• C. 32 in
• D. 36 in

Answer: (B)

The minimum height for traffic cones used on nighttime or high-speed roads is specified at 28 inches. This height is crucial because it ensures that the cones are sufficiently visible to drivers in a variety of conditions, including low-light situations. Cones that are too short may be easily overlooked, which can compromise the safety of workers and motorists alike. At 28 inches, these traffic cones provide a significant visual presence that helps to direct traffic safely and effectively. This standard height is established to enhance highway safety, ensuring that the cones can be seen from a greater distance, allowing drivers ample time to react and navigate safely through temporary traffic patterns or construction zones.
